      Work Description: bsidhom opened a new pull request #4844: [BEAM-3565] Add ExecutableStagePayload
to make aid runner stage reconstruction
   Runner code generally only has access to the root pipeline and `AppliedPTransform`s while
walking the pipeline to perform translation. This change adds a new `ExecutableStagePayload`
message which is embedded in the `FunctionSpec` of serialized `ExecutableStage` `PTransform`s.
Doing so avoids the extra pipeline munging necessary to access to proper set of subtransforms.
   It also means that subtransforms are _not_ added directly to `ExecutableStage` transforms.
This effectively makes executable stages native transforms, which they should be as far as
the runner is concerned.
   Follow this checklist to help us incorporate your contribution quickly and easily:
    - [ ] Make sure there is a [JIRA issue](
filed for the change (usually before you start working on it).  Trivial changes like typos
do not require a JIRA issue.  Your pull request should address just this issue, without pulling
in other changes.
    - [ ] Format the pull request title like `[BEAM-XXX] Fixes bug in ApproximateQuantiles`,
where you replace `BEAM-XXX` with the appropriate JIRA issue.
    - [ ] Write a pull request description that is detailed enough to understand:
      - [ ] What the pull request does
      - [ ] Why it does it
      - [ ] How it does it
      - [ ] Why this approach
    - [ ] Each commit in the pull request should have a meaningful subject line and body.
    - [ ] Run `mvn clean verify` to make sure basic checks pass. A more thorough check will
be performed on your pull request automatically.
    - [ ] If this contribution is large, please file an Apache [Individual Contributor License

> An SDK Harness executes some ("fused") collection of PTransforms. The java runner libraries
should provide some way to take a Pipeline that executes in both a runner and an environment
and construct a collection of transforms which can execute within a single environment.
